eTronix 40cm 22AWG JR Extension Wire with Male Connectors ET0757-40

Overview

The eTronix ET0757-40 is a 40cm extension wire specifically designed for RC enthusiasts who need reliable connectivity solutions for their remote control systems. Whether you're building a custom RC car UK setup, upgrading an RC aeroplane, or working on an RC boat installation, this extension lead offers the extra reach and flexibility that serious hobbyists demand. The wire features JR male-to-male connectors on both ends, making it an ideal male-to-male link for RC electronics where a longer lead or adaptor-style connection is required.

This extension wire is manufactured by eTronix, a trusted brand in the RC hobby community, and represents excellent value for money at just £1.75. The 22AWG conductor gauge is specifically engineered to suit many signal and auxiliary power runs in radio control installations, ensuring safe and reliable power delivery and signal transmission throughout your RC setup. Whether you're working on a brushless RC car, setting up servo extensions in an RC helicopter, or routing control wires in a multirotored drone, this lead provides the connection quality you need without compromise.

For RC enthusiasts in the UK looking to expand their system capabilities, this 40cm extension wire is an essential component that helps you route wiring neatly and efficiently in cars, aircraft, boats and multirotors. The standardised JR connector type ensures compatibility with a huge range of RC systems and components available on the market today.

Key Features

• 40cm length — The extended reach of this cable allows you to position components with greater flexibility within your RC chassis or frame, making it easier to achieve optimal weight distribution and component placement without cramping your installation layout.
• 22AWG conductor gauge — The 22AWG wire gauge is perfectly calibrated for signal and auxiliary power distribution in RC systems, providing excellent balance between current capacity and physical flexibility for routing through tight spaces.
• JR male-to-male connectors — Both ends feature industry-standard JR male connectors, ensuring seamless compatibility with the vast majority of modern RC receivers, servo leads, and control systems used in remote control hobby applications across the UK.
• Male-to-male configuration — This adaptor-style connection allows you to extend existing leads or link components that both have female sockets, giving you maximum flexibility in system architecture.
• Professional quality construction — eTronix build their extension wires to exacting standards, ensuring reliable connections that won't let you down during important RC sessions or competitions.
• Suitable for multiple RC disciplines — This extension wire works equally well in RC cars, aeroplanes, helicopters, boats and multirotors, making it a genuinely versatile component for any RC hobbyist's spare parts box.
• Neat cable routing — The flexible 22AWG conductors allow you to route wiring tidily within your RC model, improving aesthetics and reducing the risk of cable damage during operation.

Technical Performance

The eTronix ET0757-40 extension wire is engineered with meticulous attention to electrical safety and performance standards. The 22AWG conductor gauge provides adequate current capacity for signal distribution and low-power auxiliary circuits commonly found in RC systems, whilst remaining flexible enough for routing through confined spaces within your RC model's chassis or airframe. The wire length of 40cm (approximately 16 inches) offers substantial reach beyond standard servo and receiver leads, making it possible to position components where they provide optimal balance and weight distribution. The JR male connectors fitted to both ends are gold-plated for superior electrical contact and corrosion resistance, ensuring reliable signal transmission even after extended storage or exposure to humid conditions. The wire insulation provides good mechanical protection whilst remaining flexible throughout the full operating temperature range experienced in typical RC hobby use. Whether you're building a competition-grade RC buggy, setting up a scale RC rock crawler, or configuring a ready-to-run RC model, this extension wire meets the quality standards demanded by serious RC enthusiasts in the UK and beyond.

Frequently Asked Questions

• What is this extension wire used for in RC hobby? — This eTronix extension wire allows you to extend the reach of your servo and receiver leads, or create male-to-male links between components in your RC car, plane, helicopter, boat or drone. It's particularly useful when you need extra cable length for optimal component positioning or when adapting between systems with matching male connectors.
• Will this work with my RC transmitter and receiver system? — Yes, provided your RC system uses JR-style connectors on its servo and receiver leads. JR connectors are industry-standard across most major RC brands and are found on countless commercial RC vehicles and aftermarket components available in the UK market.
• Is the 22AWG gauge suitable for powering servos? — The 22AWG conductor gauge is suitable for many signal and auxiliary power runs in RC installations. For high-current applications or very demanding servo loads, you may want to verify compatibility with your specific servo specifications, but for standard RC receiver and servo extensions, this gauge is perfectly adequate.
• Can I use this as a male-to-male adapter? — Absolutely. This extension wire is specifically designed to work as a male-to-male link, making it ideal when both your components have female JR sockets and you need to connect them together, or when you want to extend existing leads with matching connectors.
• What makes eTronix extension wires reliable? — eTronix build their cables to professional standards with quality connectors and proper insulation. These wires are designed to provide reliable electrical connections with minimal signal loss, even after repeated use and storage typical in active RC hobby use.
• Is this suitable for beginners? — Yes, this extension wire is completely beginner-friendly. Whether you're discovering the world of RC for the first time or you're a seasoned competitor, this simple but essential component helps you build reliable systems. Installation is straightforward — simply plug the JR male connectors into matching female sockets.
• Will this work with ready-to-run RC models? — If your ready-to-run RC car, plane or boat uses JR-style connectors, then yes, this extension wire is fully compatible and can help you customise your setup for better component positioning.
• How flexible is the 22AWG wire? — The 22AWG conductor is flexible enough to route through tight spaces and around obstacles within your RC chassis, whilst remaining robust enough to withstand the mechanical stresses of typical RC hobby use without kinking or breaking.
